Victron Energy BMV-712 Smart Battery Monitor

Great unit, accurate and plenty of linking options with other victron products – Good accurate unit with clear display, common RJ12 control cabling means its easy to obtain new/customise control cable length. It needs offline data storage to be fully worth the cost. The only way to see history is by having the app running, constantly. It would be great to have the unit store even 2 weeks worth of data.
